The correct option is
C Blood without corpuscles and fibrinogen
- Serum is a clear liquid that can be separated from clotted blood.
- Plasma contains water, salt, and enzymes along with antibodies, clotting factors, and the proteins albumin and fibrinogen.
- Blood serum is blood plasma without fibrinogen i.e. whole blood minus both the cells and the clotting factors
Thus, the correct answer is option C.
